本文介绍如何使用Python的pylab库在绘图中设置右侧的标签，包括坐标轴的位置调整、文字旋转及对齐方式等。通过示例代码展示了如何实现这一功能，并解决了文字超出坐标轴范围被裁剪的问题。

To make a ylabel on the right, use the text command. You need to set
the transform to use axes coordinates (ax.transAxes), rotate the text
vertically, make the horizontal alignment left, the vertical alignment
centered. Note that x, y = 1, 0.5 is the right, middle of the axes in
axes coordinates. You also need to turn off clipping, so the text can
appear outside the axes w/o being clipped by the axes bounding box,
which is the default behavior.

from pylab import *

plot([1,2,3])

text(1.02, 0.5, 'volts',
horizontalalignment='left',
verticalalignment='center',
rotation='vertical',
transform=gca().transAxes,
clip_on=False)
show()
